Definitions
- the invention relates to a method and a device for the rapid liquid chromatographic separation of substance mixtures and identification of substances according to the preambles of claims 1 and 5.
- the problem in pharmaceutical research is to isolate pharmaceutically active substances from substance mixtures. Natural product extracts or mixtures of substances generated by combinatorial chemistry are tested for their potential effectiveness. From substance mixtures that have shown effectiveness, an attempt is then made to isolate the active substances using complex separation processes. The individual substances of the mixture isolated in this way are then subjected to a new activity test. The structure of the effective individual substances now found is examined in order to rule out possibly already known active substances.
- a disadvantage of this method is that the effectiveness of individual substances can be suppressed in the test of the substance mixtures by means of superimposition effects and these remain undetected.
- overlay effects can pretend to be effective and then it is searched in vain for these supposed active substances in the substance mixture in vain.
- the invention is based on the object of offering a device and a method for liquid-chromatographic separation, isolation and identification of substances in the analytical and semi-preparative field, with which a test for the effect of substance mixtures is unnecessary and it is possible to separate substance mixtures faster than previously, isolate and identify the individual substances.
- the invention has several advantages.
- the substances no longer have to be tested twice, namely beforehand in the mixture of substances and after isolation.
- the time-consuming and costly first test of the substance mixtures which is sometimes flawed, can be omitted.
- the previously costly processing of known substances is no longer necessary.
- the time and cost involved in determining a new active substance can be significantly reduced.
- this procedure is safer because the test results on unknown individual substances are clear and all active substances present in the mixture are also recorded.
- the substance mixtures to be investigated are processed in a two-stage separation.
- the second chromatographic separation stage several fractions from the first separation step can be separated in parallel by the inventive connection of separation columns and solid-phase extraction columns (collecting columns) with the pump unit.
- this device works much faster and therefore cheaper than known two-stage devices.
- the individual substances are identified by known direct computer-controlled comparison of the chromatograms and spectra obtained from detectors and the retention area from the first separation step and the Retention time from the second separation step with information about known substances in a database.
- Ultraviolet absorption, mass spectrometry, light scattering, fluorescence, infrared spectroscopy and nuclear magnetic resonance spectroscopy are possible as detection and identification principles.
- the inclusion of further identification parameters such as B. Source and origin of the sample is possible. Since fewer tests are necessary to identify the substances in the mixture and to exclude substances that are already known, this system can be dimensioned on an analytical and semi-preparative scale. Analytical and semi-preparative systems are much cheaper to purchase and operate than the previously used preparative systems. Due to the lower consumption of solvents and buffer substances, the method and the device according to the invention are environmentally friendly due to the lower amounts of waste.
- 2 shows a schematic illustration of the separation of a substance mixture in the first separation step and adsorption of fractions on the first collecting column battery
- 3 shows a schematic illustration of the separation of a substance mixture in the first separation step and adsorption of fractions on the second collecting column battery
- Fig. 6 is a schematic representation of a parallel separation of absorbed fractions in the second separation step
- FIG. 7 shows a schematic illustration of the equilibration of a collecting column battery.
- 1 to 7 show an example of the structure and flow diagram of a device according to the invention with a separation column and three subordinate separation lines.
- a pump unit 2 which consists of three pumps 2.1 to 2.3, is via the 6-way 2-position valves 3.1 and 3.3 and the 3-way 2-position valve 5.7 with a charging column battery 6, a separation column 10, for the first separation stage and a second separation stage, which consists of three separation lines that can be operated in parallel, each of which is preceded by a 6-way, 2-position valve 3.5, 3.6 and 3.7, connected.
- This makes it possible to transport the mobile phase in any desired composition one after the other and in parallel into all areas of the device.
- Each dividing line has a collecting column battery 7, 8 and 9 and a separating column battery 11, 12 and 13.
- the collecting column battery 7 contains the collecting columns 7.1 to 7.6 and the separating column battery 11 contains the separating columns 11.1 and 11.2.
- the two other dividing lines shown are constructed identically.
- Other variants with more feed columns 6.1 to 6.6 of the feed column battery 6, a plurality of separation columns 10, more than three collecting column batteries 7, 8 and 9, each with more than six collecting columns and more than three separation column batteries 11, 12 and 13 with more than six separation columns per battery are possible .
- the separation column 10 is equilibrated.
- the air from the Feeder battery 6 removed.
- the air is removed from one of the dry-filled feed columns 6.1 to 6.6 with water, the next to be injected.
- the separation column 10 is equilibrated with a suitable solvent by means of the pump 2.1, the 6-way 2-position valves 3.1 and 3.3.
- the separation program is started. First the 6-way 2-position valves 3.3 and 3.5 are switched. The components of the mobile phase can be entered into the system by means of the pump unit 2 via a low pressure valve unit 1 with the low pressure valves 1.1 to 1.3. The mobile phase is transported via the low-pressure valve 1.1 of the pump 2.1 and the pump 2.1, whereby this system can be operated both isocratically and with a gradient. Via the 6-way 2-position valve 3.3 and the 7-way 6-position valves 4.1 / 4.2, the mobile phase of pump 2.1 is guided to the feed column 6.1 to 6.6 from which sample material is to be processed.
- the sample to be separated is transferred from one of the feed columns 6.1 to 6.6 to the separation column 10.
- Those emerging from the separation column 10 Separate test components pass through a 6-way 2-position valve 3.4 and the detector 14.1 to a T-piece 17, where water is mixed into the mobile phase via the pump 2.2 and the 6-way 2-position valve 3.1.
- the amount of water mixed depends on the polarity of the substances to be separated.
- the polarity of the mobile phase which is increased by water, now enables adsorption on the collecting columns 7.1 to 7.6 of the collecting column battery 7.
- Via the 6-way, 2-position valve 3.5 adsorption onto the collecting column battery 7 is first carried out.
- the collecting columns 7.1 to 7.6 are covered with fractions one after the other.
- the separation column batteries 11, 12 and 13 are equilibrated.
- 5 shows the equilibration of the separating column batteries 11, 12 and 13.
- the mobile phase is led via the pump 2.1, the 6-way 2-position valve 3.1 and 3.5 to the separation columns 11.1 and 11.2 of the separation column battery 11. From there, the mobile phase is led into the waste via the 6-way 2-position valve 3.4, the detector 14.1 and a fraction collector 15.1.
- the separation columns 12.1 and 12.2 of the separation column battery are equilibrated via the pump 2.2, the 6-way 2-position valves 3.1 and 3.6 as well as a detector 14.2 and fraction collector 15.2.
- the separation columns 13.1 and 13.2 are equilibrated in parallel via the pump 2.3, the 6-way 2-position valve 3.7 and the 3-way 2-position valve 5.7 as well as a detector 14.3 and a fraction collector 15.3.
- the mobile phase is guided to the collecting column battery 7 via the pump 2.1 of the pump unit 2 and the 6-way 2-position valves 3.1 and 3.5.
- the first eluted fraction from the collecting column battery 7 (e.g. from collecting column 7.1) is conducted via the 6-way 2-position valve 3.5 to the separating column battery 11.
- the separated components are then led to the detector 14.1 via the 6-way 2-position valves 3.5 and 3.4.
- the software in the electronic control unit evaluates the signals with the aid of peak detection and directs the separated components into the corresponding vials of the fraction collector 15.1. At the same time, time control of the fraction collector 15.1 is also possible. This timing can be activated automatically if no peak passes the detector.
- the mobile phase is conveyed to the collecting column battery 8 via the pump 2.2 and the 6-way 2-position valves 3.1 and 3.6.
- the first eluted fraction from the collecting column battery 8 (e.g. from the collecting column 8.1) is conducted to the separating column battery 12 via the 6-way, 2-position valve 3.6.
- one of the separating columns 12.1 or 12.2 can be switched on under software control.
- the separated components are led to the detector 14.2.
- the software evaluates the signals with the help of peak detection and then directs the separated components into the corresponding vials of the fraction collector 15.2.

- FIG. 7 shows the equilibration of the collecting columns 7.1 to 7.6 of the collecting column battery 7.
- the collecting columns 7.1 to 7.6 are rinsed with water and thus prepared for the next run. This is done sequentially via the pump 2.2, the 6-way 2-position valves 3.1, 3.5, 3.6, 3.7 and the 7-way 6-position valves 4.3 / 4.4 of the collecting column battery 7.
- the equilibration of the collecting column batteries 8 and 9 is done analogously.
- the 6-way 2-position valves 3.5 and 3.6 are switched and the 6-way 2-position valves 3.1, 3.5, 3.6, 3.7 and the 7-way 6-position valves 4.5 / 4.6 of the pump 2.2 Catchment Column battery 8, the collecting columns 8.1 to 8.6 are equilibrated.

- chromatograms, retention data and spectra are collected via detectors 14.1, 14.2 and 14.3, processed directly in a computer and compared with the data of known substances. In this way, substances already known online can be identified and sorted out. In case of doubt, additional data that is obtained offline after separation and isolation can be used for identification.
